Definitions

  • This invention generally relates to motor vehicle fuel tanks.
  • Fuel tanks for motor vehicles generally have a reservoir or baffle to contain a minimum amount of fuel. These reservoirs and baffles are useful for concentrating fuel for delivery to an engine by a fuel pump or fuel pick-up tube.
  • the reservoirs are shaped to contain a volume of fuel when the tank is relatively empty.
  • baffles which are useful in preventing fuel from flowing to an area remote from the fuel pump or fuel pick-up tube when the vehicle is on an incline or changing direction or speed. Both reservoirs and baffles are useful in preventing fuel starvation to the engine.
  • U.S. patent 4,526,286 teaches a moulded plastic fuel tank having an integral splash baffle. Walls are moulded on mutually opposite sides of the fuel tank and are joined to one another. An opening in the wall permits the flow of fuel through to an area confined by the splash baffle. A non-return valve may be attached to the baffle at the opening to prevent fuel from spilling out of the splash baffle area as the vehicle accelerates.
  • U.S. patent 4,453,564 teaches a plastic fuel tank having C-shaped baffles moulded therein.
  • the baffles are moulded into both an upper and lower half-shell and then welded together.
  • U.S. patent 4,708,170 teaches the moulding of a fuel reservoir having two C-shaped projections on one wall of a fuel tank.
  • a parison is extruded within a moulding chamber having a die conforming to the reservoir shape.
  • the parison is inflated and takes the shape of the die.
  • the reservoir is integrally formed within the fuel tank walls.
  • a fuel tank prefferably has a reservoir and integral splash baffle.
  • the reservoir should confine a minimum amount of fuel when the vehicle is on an incline in any direction or when the vehicle has undergone acceleration, deceleration, or a change of direction.
  • the present invention provides a fuel tank comprising a generally planar fuel tank bottom and an upstanding wall on the fuel tank bottom.
  • the wall forms a reservoir area for containing fuel.
  • a passage within the wall has a throat area for admitting fuel to the reservoir.
  • a baffle attached to the wall and placed adjacent the throat area deflects fuel away from the passage.
  • the reservoir acts to confine fuel within an area to be withdrawn by a fuel pump or pick-up tube and supplied to an engine.
  • the reservoir is designed to contain minimum quantities of fuel, regardless of the orientation of the vehicle, that is, regardless of whether the vehicle is on level ground, climbing or descending a hill, accelerating, decelerating, or travelling around a corner.
  • the reservoir wall was three wall sections integrally moulded with the fuel tank.
  • the wall sections encircle a reservoir area for retaining fuel. Portions of the wall are in overlapping, juxtaposed relationship and form a shell or spiral shape.
  • a first wall section generally defines the reservoir area confining a quantity of fuel.
  • a second wall section extends away from the reservoir area and retains fuel when the vehicle is inclined along a transverse vehicle axis, such as would occur when going down a hill.
  • a third wall acts to retain fuel within the reservoir when the vehicle is inclined along a longitudinal vehicle axis with the right side elevated. Directions such as uphill or right-side are based on the orientation of the invention in the fuel tank. Rearrangement of the invention reorients the relative terms of uphill or right-side.
  • a baffle attached to the first wall section acts to deflect fuel within the reservoir area as the vehicle is inclined along the longitudinal axis with the right side elevated.
  • An inlet passage defined by overlapping sections of the wall admits fuel to the reservoir area.
  • Located between the baffle and the third wall section is a throat communicating with the passage.
  • the passage has a threshold with a height approximately level with or slightly above the fuel tank bottom. The threshold height in part determines the quality of fuel remaining in the reservoir. This threshold height may be easily changed to adapt the reservoir for applications requiring greater or lesser minimum fuel volumes.
  • said fuel tank is made of polyethylene.
  • the present invention provides an easily manufacturable and low-cost fuel tank having a reservoir which permits the retention of fuel as the vehicle is inclined or driven.
  • the splash baffle and the reservoir shape retain fuel in a confined area for delivery to a fuel pump or pick-up tube as the vehicle accelerates, decelerates, or corners.
  • FIG. 1 shows the rear portion of an automobile in phantom lines having a fuel tank with an integral reservoir in accordance with the preferred embodiment of the present invention.
  • a plastic fuel tank 10 is generally located in the rear section of the vehicle. Integrally moulded with fuel tank bottom 12 is upstanding wall 14 that defines a reservoir 16. Passage 18, defined by overlapping portions of wall 14, admits fuel to reservoir 16. The purpose of the reservoir is to concentrate the remaining fuel in a fuel tank for delivery to an engine. Reservoirs also act to restrain the movement of fuel within the tank while the vehicle is changing direction or speed. Unrestrained fuel movement may starve the engine of fuel, or provide inaccurate reading by a fuel level sensor.
  • FIG 2 is a perspective view of the fuel tank 10 and reservoir 16 shown in Figure 1.
  • Fuel tank 10 is shown broken-away and reservoir 16 is shown unitary.
  • Plastic fuel tank 10 has a generally flat bottom 12. Integral with bottom 12 is upstanding wall 14.
  • Wall 14 collects fuel within fuel tank 10.
  • Wall 14 has three wall sections 26, 28, 30 arranged in a generally spiral fashion defining reservoir 16. In the preferred embodiment of the invention, the wall sections are manufactured to be integral within one another and are formed from a single parison material. Wall 14 may alternatively be manufactured in three or more pieces and assembled to form reservoir 16.
  • First wall section 26 is generally circular and defines the main reservoir area 27.
  • First wall section 26 has a first end 36 and a second end 38.
  • Second wall section 28 is slightly curved and is attached to second end 38 of first wall section 26. Second wall section 28 generally extends beyond the perimeter of the main reservoir area 27.
  • Second wall section 28 has a height equal to wall section 26 at one end and tapers down to the surface of the fuel tank bottom 12 at its terminal end.
  • Third wall section 30 is spaced concentric to and spacially within second end 38 of first wall section 26.
  • Third wall section 30 comprises first end 40 and second end 42.
  • First end 40 is attached to first end 36 and second end 42 extends within reservoir 16 and concentric with first wall section 26.
  • First end 40 tapers from a height equal to first end 36 to second end 42 which has a height slightly above the fuel tank bottom.
  • Splash baffle 20 is attached to first wall section 26 and extends radially within reservoir 16 a distance approximately even with third wall section 30.
  • baffle 20 is integral with first wall section 26.
  • Baffle 20 is spaced apart from second end 42.
  • the space between second end 42 and splash baffle 20 defines throat 22.
  • the space between third wall section 30 and first wall section 26 defines raceway 32.
  • Throat 22, raceway 32, and well 34 all comprise passage 18 and permit fuel to enter reservoir area 27 from fuel tank 10. Passage 18 supplies fuel to reservoir 16 when the fuel level in fuel tank 10 is below the height of wall 14.
  • the configuration and height of wall 14 is based in part on the overall fuel tank height and the type of fuel pump or pick-up tube used.
  • Tall fuel tanks i.e., fuel tanks having a height greater than their width
  • Thin fuel tanks i.e., fuel tanks having a width greater than their height
  • the volume of wall 14 is minimised to permit fuel tank 10 to contain a maximum quantity of fuel. Also, when moulding fuel tanks from plastic material, a tall wall is more difficult to form by blow-moulding than a lower wall.
  • the fuel filler pipe shown in Figure 1 dispenses fuel directly to passage 18. This permits an engine to restart after empty using a small quantity of fuel.
  • Fuel filler pipe 19 is angled to direct fuel toward passage 18. Although the reservoir described may be placed in any within the fuel tank, preferred is with passage 18 pointing toward the side of the vehicle. Shown is fuel tank 10 positioned to have passage 18 generally facing the left-rear side of the vehicle. It is preferred that passage 18 be located on the same side of the vehicle as fuel filler pipe 19. When the fuel tank is emptied to the point where the fuel pump or pick-up tube is not operable, a small quantity of fuel can be added to the tank through filler pipe 19 and becomes concentrated in reservoir 16. Reservoir 16 should be at the lowest level of the tank when the vehicle is level to receive all the available fuel.
  • Figures 3-6 are cross-sectional views of reservoir 16.
  • Figure 3 is a cross-sectional view of the splash baffle 20 taken along the lines 3-3 in Figure 2.
  • Figure 4 is a cross-sectional view of reservoir 16 taken along the lines 4-4 in Figure 2.
  • Wall 14 forms fuel reservoir 16.
  • First wall section 26 rises to a height above the fuel tank bottom 12.
  • Third wall section 30 is spaced concentric to and within first wall section 26.
  • Third wall section 30 tapers at second end 42 to a height slightly above fuel tank bottom 12.
  • Raceway 32 is contained between first wall section 26 and third wall section 30. Raceway 32 has a threshold height 24a which determines the amount of fuel remaining in the reservoir as the fuel tank empties.
  • threshold height 24a Shown as solid line 24a, is the lowest threshold height which is approximately level with the fuel tank bottom. This height retains the least amount of dead fuel within the tank. In the embodiments developed by applicants, threshold height 24a retains approximately 1.5 litres of dead fuel in reservoir 16 when fuel tank 10 is level. Threshold height 24b was found to retain approximately 1.6 litres of dead fuel, threshold height 24c was found to retain approximately 1.7 litres of dead fuel, and threshold height 24d was found to retain approximately 1.8 litres of dead fuel. Only slight modifications of the tooling permits manufacture of a fuel tank with a different threshold height.
  • fuel tank 10, bottom 12, and wall 14 are preferably made of a single blow-moulded material; however, reservoir 16 may be fabricated separately and subsequently attached to a fuel tank. It is also possible to form fuel tank 10 or reservoir 16 by injection or compression moulding. It is preferred to form fuel tank 10 from a thermoformable material, but thermoset materials or even steel may be used.
  • the preferred embodiments of the fuel tank shown in Figures 1-6 is manufactured by blow-moulding.
  • a mould having a die in the shape of reservoir 16 is provided.
  • a hollow parison of pliable polymeric material is extruded within the mould.
  • the mould and die are closed to seal the periphery of the parison.
  • the parison is inflated and forced to take the shape of the die.
  • the parison closely conforms to the die and is permitted to cool.
  • the finished article is removed from the mould for further processing and assembly into a vehicle.
  • a variety of materials are useful in blow-moulding applications, but specifically preferred for automotive fuel tanks is high density polyethylene.
  • threshold heights 24a-d Projections within a die (not shown) form threshold heights 24a-d.
  • thermoplastic material such as polyethylene
  • the threshold height of the cooled tank was found to be slightly higher than would otherwise be expected from the die shape; this was due to shrinkage of the plastic.
  • the die should be slightly undercut, or made deeper, to compensate for plastic shrinkage. This would not be a factor if reservoir 16 is made from a material that does not shrink when cooled.
  • reservoir 16 When fuel tank 10 is full, reservoir 16 is submerged beneath the fuel. As the fuel tank empties, wall 14 is above the level of the fuel. When the fuel tank is nearly empty, a quantity of dead fuel, generally about 1.5 litres, remains within reservoir 16 when the vehicle is approximately level. As stated previously, the amount of fuel remaining in the reservoir is determined by threshold height 24a-d. Reservoir 16 also acts to concentrate the remaining fuel for delivery to a fuel pump as the vehicle undergoes acceleration, deceleration, cornering, or when the vehicle is on an incline.
  • Figures 7a-7d are plan views of reservoir 16 showing the fuel remaining in reservoir 16 as the vehicle is inclined or driven.
  • Figure 7a shows the fuel remaining within reservoir 16 when the vehicle is inclined about longitudinal vehicle axis B with the left side higher than the right side or while the vehicle is cornering toward the left.
  • Fuel enters reservoir 16 through passage 18 and excess fuel spills over first wall section 26.
  • the inertia of the remaining fuel in reservoir 16 forces a wave of fuel toward the right of the vehicle.
  • the wave of fuel rebounds against first wall section 26 and is contained within reservoir 16 when the vehicle returns to a level or straight condition.
  • Figure 7b illustrates the fuel remaining in reservoir 16 when the vehicle is inclined about transverse vehicle axis A with the rear end higher than the front end, such as when the vehicle is descending a hill or when the vehicle is undergoing deceleration.
  • the fuel enters passage 18 and partially concentrates in well 34.
  • Second wall section 28 contains fuel in well 34 and makes it available to the fuel sender or pick-up.
  • Figure 7c illustrates the remaining fuel in reservoir 16 when the vehicle front end is inclined along axis A with the front end higher than the rear end, such as when a vehicle is climbing a hill or when the vehicle is undergoing acceleration.
  • Figure 7d illustrates the fuel remaining in reservoir 16 when the vehicle is inclined about axis B with the right side higher than the left side or while the vehicle is cornering toward the right.
  • Baffle 20 deflects the return wave of fuel from flowing out into passage 18.
  • the volume of fuel remaining in reservoir 16 is determined by the height of first wall section 26 with respect to the fuel tank bottom. It is desirable that 400 ml or more of fuel remain in reservoir 16 under any of the above identified conditions.
  • Fuel moving within reservoir 16 is generally described as "slosh". Fuel slosh is generally contained within reservoir 16 by wall 14 and baffle 20. Fuel moving from the right side of the vehicle to the left side of the vehicle is prevented from spilling out of the reservoir by baffle 20. Baffle 20 directs fuel away from throat 22 and raceway 32. Fuel moving from the left side of the vehicle to the right side of the vehicle is also directed away from throat 22 by third wall section 30. Fuel slosh induced by incline, acceleration, deceleration, or cornering remains confined within reservoir 16.
  • the invention has been described as an integrally moulded reservoir in a fuel tank.
  • the reservoir may be made from separate pieces and placed within a plastic or metal fuel tank.
